    Sounds like the drain tubes are blocked, very common. Do a search here for clogged drain tubes. Both my rear lines were plugged solid

    It may be the drain tubes. I ran weed eater line in the front passenger drain. Ran a waterhose, and i get only a couple of specks of water on that front seat, whereas before, it was a steady drip, along with the headliner on that side being wet. So, i hope that solved it.....

    Down at the lower ends of the 4 drain tubes - near the inner corners of the wheelwells basically under the A-pillars and sail pillars - there are razzmatazz flappers - designed to keep air and bubbling noises from coming back into the cabin. Find each one and massage it - or simply cut it off.

    While you're under the front passenger side, find the A/C condensate drain elbow and clean it out too: Fall weather, particularly in the morning, can be humid as all get-out and the system will pass off a LOT of distilled water.
